Casino is an institution in which people can gamble and play games of chance, including poker, blackjack, roulette, slot machines, craps, keno and baccarat. In addition to gambling, casinos are also often known for their live entertainment, shopping, top-notch hotels and restaurants.

Like any business, a casino has a built-in advantage to ensure that it, and not the customers, will win in the long run. This advantage is mathematically determined and is known as the house edge. This advantage is the gross profit that the casino expects to make on each game played, although individual patrons can win or lose. Because of this, it is very rare for a casino to lose money in a given day. To entice big bettors, casinos regularly offer them extravagant inducements such as free spectacular entertainment and luxury living quarters. Lesser bettors are offered reduced-fare transportation, hotel rooms, free drinks and cigarettes while gambling and other incentives.

Casinos are a major source of entertainment for tourists and can bring in billions in profits each year. However, critics argue that they shift spending from other forms of local entertainment and can cause problems such as compulsive gambling. Furthermore, they may harm economic development by reducing property values and creating a class of affluent gamblers who spend more than they win.

The casino industry has changed dramatically in recent decades. Once owned and operated by mobsters, many of the world’s largest casino chains have bought out the mob and moved away from Mafia involvement. The industry is also facing increasing competition from online gambling and the expansion of state lotteries.
